title: [Aggregation inhibiting and anticoagulant effects of oligoamines. 13. Improvement in the storage of whole blood and erythrocyte suspensions with oligoamines].
abstract: The impairment of the functions of red blood cells or their destruction during storage can be delayed or even inhibited by oligoamines especially RE 1492 (N,N',N''-Tris-(4-phenylbutyl)benzene-1,3,5-trimethanamine). When citrated whole blood (WB) is stored at 4 degrees C for 7 d half of the red blood cells (RBC) have lost their ability to form rouleaux. Addition of 100 mumols/L RE 1492 maintains 50% reaggregability up to day 28th of storage. When citrated WB is stored at 37 degrees C the reaggregability has declined to 40 percent after 10 h. With 100 mumols/L RE 1492 no reduction of this property is observed up to 48 h. These results are correlated with the maintainance of the discocyte form of RBC and a persistent filtrability of RBC suspensions through a 5 microns microporous membrane. With 100 mumols/L RE 1492 only one fifth of the haemolysis of untreated WB occurs. The efflux of potassium ions from RBC into the blood plasma during a 72 h storage is bisected by RE 1492. The binding of oxygen to RBC remains unchanged.
